sqlx example doesn't seem to work

[HenrikPoulsen]

First time using musttag and sqlx.
I tried out the below config, which is the one recommended, which did not detect any issue

      - name: github.com/jmoiron/sqlx.Get
        # The struct tag whose presence should be ensured.
        tag: db
        # The position of the argument to check.
        arg-pos: 1

Whereas changing it to the following seems to work

      - name: (*github.com/jmoiron/sqlx.DB).Get
        # The struct tag whose presence should be ensured.
        tag: db
        # The position of the argument to check.
        arg-pos: 0

Code snipped I used for testing as follows:

type SchemaMigrations struct {
	Version int
	Dirty   bool
}


var migrations SchemaMigrations

err = conn.Get(&migrations, "select * from schema_migrations where version = $1", 1)
if err != nil {
    log.Fatal(err)
}

(*github.com/jmoiron/sqlx.DB).Get does call github.com/jmoiron/sqlx.Get so I would have assumed it would still work.
But I don't really know anything about how these linters work.
Just wanted to flag this. For my usecase I'll just add the extra config

Hello @HenrikPoulsen,

This example only covers the package-level sqlx.Get function, which is not the same as the sqlx.DB.Get method. You're absolutely right with the config you provided above, to detect issues with the latter, the (*github.com/jmoiron/sqlx.DB).Get function name should be specified.

I can now see why this example may be confusing, since Get as a method is definitely used more often. Thank you for pointing that out!

Anyway, I'm about to add support for sqlx out of the box in #6, so no additional configuration will be needed in your use case.

@HenrikPoulsen fyi, builtin sqlx support has been merged in v0.7.0
